基于GML的铁路地理信息系统共享中间件技术

Technology of shareable RGIS middleware based on GML

采用GML-XML技术,在异构分布式地理信息数据之上,建立地理信息共享中间件,以屏蔽不同数据源的差异,使得来自于分布式数据源的异构空间数据融合为具有一致结构的数据,以进行统一管理,并能够满足铁路运输业务的特殊需求。通过B/S架构,用户使用浏览器可以方便、高效地访问铁路空间地理信息数据。

It was introduced the technology of GML-XML into RGIS field. Base on the distributed and different constructedGIS data, it was set up the shareable middleware to shield the difference of the data format, then managed these data uniformlyby the consistent data structure to satisfy the particular needs of the railway transportation.Using B/S architecture, thecustomer could visit the railway GIS data conveniently and efficiently by the internet browser.
